Active Noise ReductionHearing Protection

What is active noise reduction hearing protection? Does it work? It is worth the cost?

Active noise reduction (ANR), also known as noise cancellation technology, is
used in many high-end headphones,
to enhance the music sound quality by reducing noise from the external environment. It is also used in some hearing protection devices.

Active noise reduction
is circuitry that reads the incoming sound waves, electronically inverts them by phase, and plays the resulting inverted sound waves. Added to the external sound waves in this way, the phases cancel each other out, bringing the amplitude (volume) near zero.

ANR hearing protection does have application in aviation and military environments, in conditions of extreme noise where speech communication is necessary — for example, by helicopter pilots, airport ground crew, and armored tank crew.
